SPECIFICATION forming part of Letters Patent No. 441,441, dated November 25, 1890. t

Application filed February 23, 1888- Serial No. 264,899. (No model.)

To a/ZZ whom it may concern:

Be it known that I, SAMUEL D. PALMER, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Churns, of which the following is a specification.

This invention consists of an annular metallic ring-head and a removable head held in place on the ringheadin a removable manner by means of bails pivoted to the ringhead and iitted with cam projections to engage the removable head. To this end I have designed and constructed the churn represented in the accompanying drawings, in which Figure I is a plan View of a churn embodyingmyinvention. Fig. 2 is a plan view ot` the removable head. Fig. 3 is a transverse ver` tical central section. Fig. 4 is an enlarged view of a portion of a bail, showing the cam. Fig. 5 is also an enlarged view of a portion of a bail, showing a cam having a grooved face. Fig. 6 is a perspective view showing the bails in a vertical position to permit of the cover being removed or put on 5 and Fig. 7 is a vertical sectional view taken on line x Fig. 6, showing the bails in full lines in a position for removing the cover and showing them in dotted lines for clamping the cover in position.

In the figures, l represents an annular metallic ring-head tted to enter the croze of the churn and having ears 2 rising from its upper face at proper intervals. This annular ring-head is fitted on its inner edge with an uprisingbead=formed seat 3 to receive the packing of the removable head. The removable head consists of an annular metallic ring of angle-iron form in section, which receives the main portion 5 of the head. The outer edge under face of the head is recessed and an annular packing-ring 6, of cork or other suitable material, is placed within the recess. The annular ring 4 is provided with a transverse center bar 7, from the center of which rises a suitable handle 8 for the convenience of handling the removable head. The periphery of the annular ring of the removable head is formed with projections 9 at proper inter vals to enter between the uprising ears of the bails have their end portions produced in' cam-formed projections 12, having their periphery eccentric to the pivotal support of the bail in such a manner than when the bails are swung outward the cam-formed pro-v jections 12 will engage theupper surface of the peripheral projections 10 of the removable head in a manner to press it to its seat with sufficient force to produce a Water-tight connection of the head with the ring-head.

A notch 13 is formed between the peripheral projections 9 and 10 of the ring-head to receive the inner edge portion of the bails when in a vertical position to permit the head to be put in place on the annular ringhead or removed therefrom. In this instance I have represented the cams 12 with a smooth peripheral face to engage the projection 10 of the removable head, which construction I prefer; but instead of the smooth peripheral face grooved cam-faces may be employed, as shown at Fig. 5.

To readily place the removable head in position on the annular ring-head, turn the bails outward. Then place the removablehead in position to enter Within the uprising ears. Then turn the bails inward, which Will permit the removable head to drop in place on Then turn the bails outward,-

the ring-head. which movement will bring the cams in contact with the projections 10 of the removable head and press it to its seat on the ringhead.

So far as known to me I am the first to employ a pair of bails provided with self-locking cams which engage and hold -the removable head in position. Therefore it is immaterial where the bails are pivoted to j the churn, by which term I mean to embrace the churn-body, ringhead, or removable head, so long as they have the self-locking cams, and I consider any of the above locations within the scope. of my invention.

I claim as my invention@` IGC l. The combination of achurn, a removable head adapted to be placed on and removed from the churn in the direction of its length, and a pair of bails pivoted to the churn, said bails provided with self-locking cams which engage and hold the removable head in position, substantially as setforth.

2. rlhe combination of a churn, a removable head adapted to be placed on and removed from the churn in the direction of its length, two pairs of ears secured to the churn, and a pair of bails pivoted to the ears, said bails provided with self-locking cams which engage and hold the removable head in position, substantially as set forth.

3. The combination of a churn, a removable head, a ring-head on which the removable head rests, a pair of hails pivoted to the churn, said bails having self-locking cams which engage and hold the removable head in position, substantially as set forth.

4. The combination of a churn, a removable head, aring-head engaged thereby, two pairs of ears secured to the churn, a pair of bails pivoted to the ears, said bails having selflocking cams which engage the removable head, holding it in position, substantially as set forth.

5. The combination of a churn-body, a ringhead, a removable head, a pair of bails pivoted to the ring-head, said bails provided with self-locking cams which engage the removable head and hold it in position, substantially as set forth.

6. The combination of a churn-body, a ringhead provided with ears, a removable head, a pair of bails pivoted to the ears, said bails provided with self-locking cams which enoted to the rin 9g-head, said bails provided with self-locking groove-faced cams, substantially as set forth.

t8. The combination of a churn, a removable head, and a pair of bails pivoted to the churn,

said bails provided with self-locking groovefaced cams which engage and hold the removable head in position, substantially as set forth. l

9. The combination ot' a churn, a pair of bails pivoted to the churn, wh ich are provided with self-locking cams, and a removable head provided with projections which receive the cams, thereby holding the removable head in position, substantially as set forth.

10. The combination of a churn-body, a ring-head, a removable head provided with projections, and apair of bails pivoted to the ring-head, said bails provided with self-locking cams which engage the projections of the removable head, thereby holding the removable head in position, substantially as set forth.

1l. In combination with a churn, a pair of bails pivoted to the churn and provided with self-locking cams, a removable head provided with peripheral notches to receive the bails, and with peripheral projections to receive the cams, substantially as set forth.
